5. Technical characteristics
5.1. Introduction
The "Field mill" utilized by the Previstorm® is the only system able to preventively
detect lightning phenomena. It is not necessary for a lightning strike in order to detect
some type of storm activity. Other capturing devices need lightning to strike in order to
begin the detection process, being already too late to take proper action.
Previstorm measures the electrostatic field representative of the electric storm activity
which might provoke lightning strikes if the electrostatic field overcome a detailed
value. The electrostatic field (kV/m) measures the difference of potential that there is
between the cloud and the zero earth potential per length unit.
A measure process exemple will be:
1)
2)
3)
4)
5)
Electrostatic field in normal conditions is around 0.150 kV/m
Storm starts
Alarm 1 or distant storm: reports the beginning of a storm activity
Alarm 2 or near storm, conveys the approximation or local formation of a storm
Alarm 3 or active storm, warns of a strong probability of a lightning strike within
the measured area.
6) After the alarm time defined, the alarms get automatically disactivated.
Note: The alarms levels are defined by defect but they are adjustables. Please see
chapter 8: Configuration.
The warning time depends on the cloud’s features:
Cloud’s movement speed
Cloud’s creation speed
Cloud’s dimensions
When the storm detection system’s situation is not normal:
ð height in front of the sea
ð high structure in front of the earth
ð antennes or structures proximity
the electrostatic field is deformed and the measure it is affected by an important,
constant and lineal coefficient factor. The Coefficient form corrects these situations.

6.1. Equipment Installation
The equipment operates with continuous 24 V DC power. This be either an
uninterruptible power supply with batteries, or by direct 24 V DC power supply.
Install the MCE capture device or sensor outside where the horizontal plane is as
clear from obstructions as possible (See annex). Attach the connection cable to the
MCE passing it inside the mast, and connect it to the sensor. The mast and the MAD
modules are to be grounded to earth.
Connect the following terminals:

7. Principles of Operation
The equipment operates completely automatically. Starting and stopping the
equipment is done by way of switch 13. Stopping the equipment does not erase its
configuration.
The electrostatic field is permanently display on the screen. Screen illumination
can be activated with button 5. The light will automatically turn off after 10 minutes.
When the corrected field value surpasses any of the alarm levels, the
corresponding alarm indicator light is activated and its rely is tripped. A message
appears on the screen indicating the type of alarm activated.
In the event of Previstorm® failure, the illuminated ERROR indicator lights, and
the error relay is thrown.
The buzzer incorporated in the device will activate along with any type of alarm.
When an alarm occurs, it will remain active until:
G
G
After Alarm level 1, 2, or 3, when the field level falls to levels below that of the
corresponding alarm, a period above the “Alarm Finish Time” parameter.
After an Error Alarm, when the error is resolved.
The alarms can be manually deactivated, which has the effect of stopping the audio
alarm warning, and switching the relays to their normal state. The alarm indicator light
does not switch off when canceling the alarm. The indicator will remain active while the
field measurement is superior to the corresponding alarm level.
The alarm levels and times are changed with the configuration buttons.

User Manual
To obtain the storm risk indication, 3 levels of alarms allow to control different
warning levels:
G
ALARM 1
“distant storm”, reports the beginning of a
storm activity.
G
ALARMA 2
“near storm”, conveys the approximation or
local formation of a storm.
G
ALARMA 3 “active storm”, warns of a strong probability
of a lightning strike within the measured area.
The field measurement is corrected by a form coefficient to take the influences of
the MCE sensor or capturing device location into account. This corrected field
measurement is what is presented on the system screen, and which is used to compare
with the alarm level values.
Detection reliability is important; when there is no field activity there is 100%
assurance that there is no storm risk.
The relays associated with the alarms permit:
G
Activation of visual and audio alerts. ✓
G
Inform a system which operates as central alarm control. ✓
G
Activate systems such as electric generators. ✓
G
Isolation of the installation to be protected. ✓

8. Configuration
Before starting the equipment, carefully check that all connections are correct.
8.1 System Configuration
The Equipment is started with the ON / OFF button, modify the form coefficient
to obtain the normalized value according to the placement topology. This parameter is
found in the MAC menu.
Modify the values of the Level Alarms according to the function mode desired.
It is recommended to adjust the Alarm Levels in the following order:
ALARM 1 < ALARM 2 < ALARM 3
Adjust the times according to the desired affect. In the case of it is recommended
to define the value at 10 minutes. This parameter is adjustable in the menu.
Levels recommended, already configurated at the equipment are:
Alarm 1
Alarm 2
Alarm 3
2 kV/m
4 kV/m
8 kV/m
8.2. Using the menus to adjust parameters
There are two distinct menus, one for the MCE capture device and another for
the MAD console. To access the adjustments dialog, press the menu key and the
adjustments for the MCE capture device will appear. Pressing the menu key again will
bring up the MAD controls and pressing the menu key again will return it to the work
screen.
Use the left and right arrows to advance through the various menu options until
the parameter desired is reached. To modify the menu, press the ok key and increase or
decrease the value with the up and down arrows, once adjusted press the ok key. To
exit the menu dialog press the menu again until the electric field reader screen is
reached
